immediately following the scarifying action, with the result it will be seen that positive and maximum vaccinations can be made with my instrument in minimum time, and with no waste of the vaccine.

A further object is to provide a vaccinating instrument that is primarily designed for vaccinating animals, particularly sheep and goats and due to the quick action by which the instrument can be used, very little di-fliculty is experienced in Vvaccinating the animals.

Another object isto provide a vaccinating instrument that is simple in construction, inexpensive to manufacture and extremely efficient in operation, use and service.

This invention also consists in certain other features of construction and 'in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated iin the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a side view partly i-n section of one form of my vaccinating instrument and illustrates parts in full and dotted lines.

Figure 2 is a bottom plan view of the form as shown in Figure 1.

Figure 3 is a side View of a modified form partly in section, and with parts in full and dotted lines.

Figure 4 is a longitudinal sectional view taken through another modified form.

Referring to the drawing in detail, and particularly to the form as shown in Figures l and 2, it will be noted that the instrument of that form includes a head I which is relatively narrow and formed on and extending therefrom is a relatively flat handle 2.

The reservoir of the form of Figures 1 and 2 is shown as being a cup 3 that is formed on and rises from the head I and includes a restricted lower portion for directing the vaccine therefrom to a passage 4 that extends horizontally through the head and. provides a guide for a valve plunger rod 5 that is slidably mounted in the passage 4 for ej'ecting the vaccine from the passage to the brush as clearly shown in Figure 1. 5-

The passage 4l extends through the forward end of the head, and that portion is closed by a threaded stud 6 having a kerf therein tofacilitate the application and removal thereof. When the stud is removed, it will be obvious that the passage 4 can be readily cleaned by the use of a pin, tube or the like, not shown.

Formed on and rising from the head I at the juncture of the handle therewith is a lug I having an opening therethrough, that acts as a guide means for the plunger rod, land the rod is normally held in open position as shown in full lines in Figure 1, by a coil spring v8 that surrounds the rod and has its end convolutions engaging a shoulder 9 formed on the head, and a pin I0 that extends through the rod.

In order to move the rodto closed position, against the actionv of the spring B I provide an operating member for the rod which includes a reduced end I I that is pivotally mounted between ears I2 formed on the upper end of the lug "I, and vthe operating member extends rearwardly to provide a handle portion I3, thence is looped upon itself, and terminates in a depending portion I4 disposed in contacting engagement with the outer end of the rod 5.

Mounted in the lower surface of the head I adjacent the forward end thereof are tufts of bristles providing a brush I5 and extending through the head with its inner end terminating i-n the passage 4 and its outer end adjacent to the brush I5 is a tube I6 through which flows the vaccine to supply the latter to the brush.

Arranged directly to the rear of the brush I5 are scarifying pins I1 which are beveled rearwardly, and secured tothe handle and extending forwardly therefrom to underlie the head I is a leaf spring I8 that has a notch in the forward end thereof ldisposed upon opposite sides of the pins, asbest shown in Figure 2. The leaf spring not only provides protecting means for the pins, but also facilitates the use of the instrument, as will be apparent.

The cap is provided with a cap I9 having a threaded skirt which is lthreaded within the body of the cup and disposed between the body and the cap is a gasket as shown to provide a leak proof connection.

Inasmuch as the cap' closest-'hef reservoir in an air-tight manner, the vaccine-isA retained therein against the action of gravity, but -is ejected through and from the tube I6 by the action of the plunger rod 5, which upon its return stroke Will create suction to draw a sufficient quantity of air within the reservoir, to cooperate with the plunger rod for the latter to eject the vaccine through the tube and onto the brush, as Will be apparent. l

The modified form of Figure 3 also includes a head 20 having a reservoir formed on and rising therefrom, which is likewise a cup 2|, and the` cup is provided with a cap similar to the cap I9. The lower end of the cup is restricted and communicates with a passage 22 that extends through the rear end of the head 20 and the passagehas mounted therein a plunger'rod 23 for ejecting the vaccine from the passage to the brush 24, through a tube 25 that is similar to the tube I6 and is arranged accordingly, as shown.A Scarifying pins 2B are secured to and depend from the head 20 to the rear of thebrush, consequently it will be seen that this form includes many of the elements of the form of Figures 1 and 2. The head 20 is also provided with a shoulder that forms a reduced portion 2Tft-o which is riveted or otherwise secured one of the ends o f a iiexible section 28 for the handle 29, the opposite end being iiXed to the rigid section of the handle, as shown.

Secured to and rising from the rigid section is an upright 30, and a link 3i hasione of its ends pivotally secured tothe upperv end of the upright, while its opposite end is pivotally secured to the outer end of the plunger rod 23, so that by flexing the rigid portion of the handle 29, it will be obvious that the plunger rod is moved to open and closed positions, as shown in full and dotted lines. The rod 23 is held against undue movement or stabilized by a leaf spring 32 that is secured to the reduced portion'21 and has a bowed portion contacting the underside of the rod.

In the modified formof Figure 4, the head 33 is relatively long and hasI a passage 34 extending longitudinally therethrough from end to endr the passage being enlarged at its forward portion as at 35 and the outer endther'eof is threaded to receive a headed stud 36 for closin-g the same.

The brush 31 of this form -is also secured to the forward end of the head 33 for disposal in the path of the outer end of a tube 38 that has its inner end communicating with the passage 34, and scarifying pins 39 are disposed to the rear of the brush 31.

Secured to theundersideof the head 33 is a leaf spring 49 that has its forward end terminating adjacent to the pins 39. to act as means to facilitate the use of the instrument, and of course to regulate the depth of the scraping action of the pins, as will be apparent, and the spring 40 is adjusted by a set screw 4 l.

The reservoir of this form of the invention is a tube 42 that extendsl rearwardly from the head for disposal in substantially the'same plane therewith, and the tube has its forward end threadedly secured to a nipple 43 formed on the rear end of the head in a manner to provide a shoulder for receiving the tube, as shown. The

outer end of the tube is closed by a cap 44 threadedly mounted therein, and threaded in the cap 44 is a plunger rod 45 of the screw type, the latter having a pist-on 46 secured to the inner end thereof for forcing and controlling the flow of the vaccine through the .passage 34 and the tube 38, to the brush 31.

The enlarged portion 35 of the passage 34 is adapted to receive a pin tube or the like, not shown, for cleaning and removing foreign matter from the passage, as will be apparent. The tube just mentioned can also be used for priming the instrument, if such is found to be necessary.

It Vwill be apparent that the tube 42 of the form of Figure 4 also provides a handle for the instrument.

From the above description and disclosure of the drawing, it will be obvious that l' have pro- It is to be understood that changes may bemade in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.
